Quick service response. A useful and very rare service manual with all details. I recomend this service.
;
I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
;
The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual!
I'd definitely use owner-manuals.com again.
;
Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
 ;
Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.
In such a case, check also if the POWER AMPLIFIER circuit or power supply circuit has any abnormalities or not. 2-2.
Regarding reset
There are cases that the machine does not work correctly because the MICROCOMPUTER is not reset even though the AC power cord is re-inserted, or the software reset (pressing the STOP key + POWER key) is performed. When the above described phenomenon occurs, it can leads to wrong judgement as if the MICROCOMPUTER is defective &d to exchange the MICROCOMPUTER. In such a case, perform the forced-reset by the following procedure and check good or no good of the MICROCOMPUTER. @ Remove the AC power cord.
Fig-2-2
@ Short both ends of the electrolytic capacitor Cl 13 that is connected to VDD of the MICROCOMPUTER�with tweezers. @ Connect the AC power cord again. If the MICROCOMPUTER returns to the normal operation, the MICROCOMPUTER is good. Note The reference number or MICROCOMPUTER pin number of transistor (Ql 10) and electrolytic capacitor (Cl 13) can change depending on the models. Be sure to check the reference numbers on schematic diagram before starting the discharging work.
2-3. Confirmation of soldering state of MICROCOMPUTER Check the soldering state of the MICROCOMPUTER in addition to the above described procedures. Be sure to exchange the MICROCOMPUTER after surely confirming that the trouble is not caused by poor soldering but the MICROCOMPUTER itself.
